Holy cow, she's TALL! I mean, taller than I would've guessed. I was thinking 5'6" or so. No wonder she towers over everyone in heels! (And she wears heels often!). She made Michael Buble look like a midget.

She said 5'8" in the other interview you had posted and 5'9" on Twitter. I think your original 5'8.5" listing might be more accurate as sometimes when people are a half inch over they may round up or down at different times.
